Annie Emma, Lady Thompson (née Affleck) (June 26, 1845 – April 10, 1913) was the wife of Sir John Thompson, the fourth Prime Minister of Canada. She was born in Halifax, Nova Scotia to James Affleck, a sea captain, and Catherine Saunders. She was the eldest of eight children. She has been described by historians as a high-spirited young woman who resembled Catherine Linton in Emily Brontë's Wuthering Heights. She married Thompson in 1870 in Portland, Maine.
